Nuvoco Introduces
Wet-Ready-to-Use Micro Concrete

Repair and retrofitting of existing
structures have become a major part of
the construction activity in large parts
of India wherein structures are damaged by
environmental effects, which include corrosion
of steel, variations in temperature, freeze-thaw
cycles and exposure to ultra-violet radiation.
There are always cases of constructionrelated
and design-related deficiencies that
need correction. Many structures, on the
other hand, need strengthening because the
allowable loads have increased, or new codes
have made the structures substandard. This last
case applies mostly for seismic regions, where
new standards are more comprehensive than
the old ones.
There are various methods to repair and
retrofitting of the structure, which included
Polymer Modified Mortar, carbon fibre
wrapping, jacketing with Micro concrete
(which is non-shrinking or shrinkage
compensative). The most common and costeffective
method is jacketing with micro

concrete where numerous manufacturers in
India are producing dry powder based micro
concrete in which water must be mixed
very precisely at site, as per conditions and
consultant’s specifications 10mm down
aggregates is added at site only.
Site mixing of dry mix micro concrete
is a challenge faced by repair contractors
and client as it requires skilled labour
and high level of supervision during
mixing and at the same time execution is very
slow because of all these site activities.
To overcome all these challenges in
dry micro concrete, Nuvoco developed an
innovative product, which is non-shrinking,
ready to use Instamix Microne for repair and
retrofitting of structures.
Having grown hugely popular since its
launch, wet-ready-to-use Instamix Microne
is the result of incredible disruptive innovation
in repair segment, which is conventionally
dominated by dry mix products.
Taking site repair elements into
consideration, the aggregates used vary in
size from 4.75mm to 10mm. One of the
biggest reasons for its popularity is that it
is a non-shrink product, which guarantees
excellent plastic and hardened properties. It
is extremely durable compared to the dry mix
products available in the same range. Being a
free-flowing mix, it can be used to fill all kinds
of difficult to reach areas and boasts of 30% to
40% more chloride resistance, which makes it
ideal for all kinds of aggressive environments.
Instamix Microne also offers 50% more
adhesion strength compared to conventional
products and is available in grades of M40,
M60, and M80, with a working life of five hours
after reaching the site.Typical Application
1. Extensive repair of beam, column, floor
or other structural elements
